General Motors Cadillac line has walked off with another honor. J.D. Power and Associates ranked the Cadillac DTS highest among large premium cars in its 2011 Vehicle Dependability Study released today. The DTS had 90 problems per 100 vehicles, the fewest of any vehicle in its class for the second year in a row.  For six straight years, the DTS and its predecessor, the DeVille, have earned a spot in the top three of the large premium car segment in the J.D. Power Vehicle Dependability Study. The report measures problems encountered in the past 12 months of 3-year-old vehicles.
  "DTS is part of a line of full-size Cadillac luxury automobiles known for their long-term quality and craftsmanship," said Don Butler, vice president for Cadillac Marketing. "We're pleased to have this commitment to long-term reliability confirmed by a study that means so much to consumers."  By Joseph Szczesny
